    Jul 31, 2014 Jul 31, 2014 Due to limitation of the mill’s rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5-8 mm range) improves grinding energy efficiency up to 50% using stirred mills. For specialized types of cement, which are finer
